Got a problem with my Nilfisk C110. It was all working properly when I used it on my car in the summer. Today though, when I pressed the trigger on the gun, water was coming out normally due to the hose being connected and the watermains tap turned on full, but it would take 2 to 3 seconds before the motor activated and gave pressure to the water. It kept going with full pressure as long as I kept the trigger held in but once I stopped and pressed again, it would take another 2 or 3 seconds for the motor to activate. Several minutes of pressure washing later and the delay got much longer. Any idea why this is?
As a test, I disconnected the gun from the nilfisk black hose but kept the black hose connected, turned the machine on and got instant pressured water from the hose. So it seems fine without the gun. It's when the gun is connected and the motor is activated from the trigger that there's a delay. So I don't know if there's a problem inside the machine, or if it's the nilfisk hose, or the gun.
I got all the pressure washing done fortunately. My inlet garden hose is fine, I replaced it in the summer because the previous hose was getting sucked flat. So I don't believe that is causing any issues.
